JAMES SINCLAIR, OF JORDAN, NEW YORK.

HOT-WATER HEATING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 783,472, dated February 28, 1905,

Application filed November 30, 1903. Serial No. 183,197.

To all whom, it may concern:

B'e itknown that I, J AMES P. SINCLAIR, a citizen of the United States, residing at Jordan, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Hot-VVater Heating Systems, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in hot-water heating systems, and refers particularly to a hot-water heating system with which a pressure-tank is employed; and one object of the invention is the provision of a hot-water heating system which will distribute the water evenly to all the radiators and secure a high degree of heat with the expenditure of a small amount of fuel.

Another object of my invention is the provision of a hot-water heating system in which the air will be entirely withdrawn and the water retained under the proper pressure to sustain the body of water in the radiators at the proper level at all times and positively prevent the accumulation of air in the system.

Another object of my invention is the provision of a hot-water heating system which will possess merit in point of simplicity, durability, and inexpensiveness of construction and which will be thoroughly eflicient and practical in every particular.

\Vith these objects in view my invention consists of a hot-water heating system embodying novel features of construction and combinations of parts, substantially as disclosed herein.

Figure 1 represents a side elevation of my complete system. Fig. 2 represents an enlarged detail view showing the arrangement of the exhaust-tank and air-pipe leading thereto, and Fig. 3 represents a side elevation of a slightly-modified construction of my heating system.

Referring by numerals to the drawings, the numeral 1 designates the heater provided with ihe inlet or supply pipe 2, and leading from the heater is the outflow or feed pipe 3, which leads to the radiators 4 through the medium of the branch pipes 5, having the valves 6, and from the highest radiator of the series leads the return-pipe 7 to the cold-watersupply pipe 2. Communicating with cold water-supply pipe by means of a connection 8 is the pressure-tank 9, which is provided with a pressure-gage 10 and with a water-gage 11, and communicating with said pressuretank is the air-pipe 12, which leads to the pump 13, said pump being connected by the short pipe 14 with the exhaust-tank 15, from which exhaust-tank extends the air-pipe 16, which of the pressure-tank.

8* is the service-pipe connected with the inlet or supply pipe, and 8 is an additional outflow-pipe from the heater, which may be utilized for other radiators when desired.

The operation of my system will be readily apparent. Water is admitted through the service-pipe into the inlet-pipe of the heater and passes through the latter into the outflow-phve to the base of the radiators and from the radiators through the return-pipe to the inlet-pipe and back to the heater. 'lo permit the water to rise, the air in the system is exhausted by the air-pump drawing the air from the highest point of the system into the exhaust-tank, and from the latter it is forced into the pressuretank beneath the water-level in the latter. After the system is filled with water the valve, &c., in the service-pipe may be shut off. It will therefore be understood that the air compressed in the pressure-tank sustains the water in the radiators. Any settling of the water in the highest radiator can be prevented by operating the air-pump at intervals when the gage on the pressure-tank indicates that the pressure therein is not sufficient to sustain the water at its highest elevation. The circulation of the water is facilitated by keepingthe water in the system at a higher elevation than the upper inlet to the return-pipe.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hot-water heating system comprising a heater, a water-inlet pipe connected with the base of the heater, a radiator, apressure-tank, an exhaust-tank, an outflow-pipe connecting the upper part of the heater with the lower part of the radiator, a return-pipe connecting the upper part of the radiator with the inlet-pipe, a pipe connecting the base of the pressure-tank with the inlet-pipe, a suction-pipe connecting the upper part of the radiator with the exhaust-tank, an air-pump connected with the exhaust-tank, and a pipe connecting the airpump with the lower part of the pressuretank.

2. A hot-water heating system comprlsmg a heater, an air-inlet pipe connected With the base of the heater. a radiator, a pressure-tank, an exhaust-tank, an outflow-pipe connecting the upper part of the heater with the lower part of the radiator, a return-pipe connecting the upper part of the radiator with the inletpipe, a pipe connecting the base of the pressure-tank with the inlet-pipe, a suction-pipe extending through a part of the return-pipe and connecting the upper part of the radiator with the exhaust-tank, an air-pump connected with the exhaust-tank and a pipe connecting the air-pump with the lower part of the pressure-tank.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES P. SINCLAIR.
